But I have to say, you run your mouth a whole lot for someone who's been less than helpful. Let's go over things thus far.

Congratulations, you know how to mask an issue with a 500$ band-aid and an "I know better than everyone" mindset. SFI engine have been idling around 700 for 40 years, you're not breaking new ground idling at 900.

It's the cycling of the compressor that causes the dip. If the compressor is engaged when the engine idles, the engine already is compensating for the extra load and runs smoothly. It's when the engine is idling and the compressor suddenly engages and loads down the engine is when you get the idle dip.

Make another video. This time have the AC off and not in defrost with the engine idling. Now turn on the AC. You will hear the compressor engage and at the exact same time the idle will dip.

I'll betcha.

LITTLE DID YOU KNOW! It wasn't AC that was causing OP's problem!

steve99 explainef how to fix

Oh so now you're confidently stating it's something else completely unrelated to what you were confidently stating just prior? kk cool.

steve wrote everything very good and all indexed so you ll find where he talks about idle issue

If you want spoonfeeding again... you ll find in "oft tips n tricks"

Again, your 500$ band-aid solution is unrelated to OP, yet you keep peddling it, this time with an attitude

you answered interested, and it s your problem if you doin t have a flashing device, i do not care at all

it s not going to magically change if you keep it stock... at least you found what I was referring to, it took you 2 days but it s ok

i just answered again to better remember your name and avoid answering to you totally from now on

Yes, try more attitude, see if that'll fix it!

your post is non-sense to me, also your tyre example is useless because i m only here in this forum to discuss about tunes mostly
since in this forum maybe less than 5 regular posting people know something about how the ecu works, and all the rest have no clue at all and have head filled with wrong concepts about how this car runs
i wasn t a douche
and you re just another one I will ignore

i still have lots of people writing me for help and i ll offer them for free and they are happy so your opinion doesn t touch me

If all esle fails, try still more attitude, and self-aggrandizement!

It would have cost you nothing to NOT bring your lack of contribution and attitude, but you did, and now, as if 2020 wasn't bad enough, you did.

Schweiz, I know I said I was bowing out, but one last thing... It's hard to troubleshoot over text on the internet, it's best to try and learn a lot on your end, there are a lot of small things to check, and a lot of it you can check yourself with basic tools. Going over the symptom troubleshooting section of the shop manual is a great start.

Check here https://demos.starbase7.net/t3Portal/ and navigate to 2017 repair manual, then Engine/Hybrid system > FA20 Engine Control > SFI System > Problem Symptom Table > Hunting (Poor Idling)

Some things you can check with a simple multimeter, some things you can check with a helper and something to put your ear too. I won't expect you to have a scan tool, but you may enquire at auto parts stores around your area, some may have elementary scan tools for lending/renting, just make sure it's datastream compatible for checks that require data viewing (like the MAF).
